Collection complete in box (or CiB) games is fun but also expensive. And so you usually end up with a lot of loose game cartridges for various consoles. This gets messy real soon, but there is a solution.
A viewer of RetroGameCouch (thank you Thomas!) contacted me because he wanted to donate a box with 100 universal game cases. Their universal because they can store Mega Drive/Genesis cartridges (including the bigger EA cartidges), N64 cartridges, SNES cartridges (both PAL and NTSC) and even CD jewel cases.
All you have to do is print a cover and you’re all set.
